amino acids

I am a mathematician and I have just joined this group.
Please note that I am a tyro in this area.
Recently I begin to take amino acid supplements,especially
L-lysine. As a consequence, my mood has changed in a very
positive way.
There has also been another positive benefit. The vitreous
in my eyes has partially changed to liquid and hence I have
flashes. I seem to have more of them when I am hungry.
I have always consumed lots of protein. Could it be that
my body does not efficiently change protein into amino
acids? I would appreciate any feedback.
With best regards,
